Description
Technical field
The present invention relates to a kind of passenger car safety air bag outside cars based on rolling protection, are particularly suitable for passenger car and passively pacify
Full technical field.
Background technique
According to the statistical data of NTHSA United States highways management board, rolling is breakneck accident form, than it
The collision accident of his type has the higher death rate.In 2010,9,100,000 cars, SUV, pick up and lorry, the hair of rollover accident
Raw rate only has 2.1%.But the caused death rate of rollover accident but accounts for the 35% of entire traffic accident.Only 2010
It is 1 year, dead in rollover accident more than there is 7600 people, wherein there is 69% people there is no wear safety belt.
According to 2010 year traffic accident statistics ,-four item number of Crash characteristics according to statistics: generation rollover accident 5440 in 2010
It rises, accounts for sum 2.48%.But death toll 3570, account for the 5.47% of sum.
Domestic in recent years to rise SUV upsurge, the high SUV generation rolling probability of vehicle body center of gravity is bigger, the raising of speed and SUV
The increase of occupancy volume domestic rolling probability of happening will be made higher and higher.
Although ratio of the accident in whole traffic accidents caused by automobile overturns is little, the wound of the personnel caused by overturning
It dies but quite serious.
Roof strength is for having an important influence the injury of occupant in the rollover of vehicle body.At present both at home and abroad for riding
Vehicle roof strength has relevant statutory standard, and the FMVSS 216 in the U.S. and domestic GB 2161314-2012 have roof strength
Specific standard.
Relevant criterion both domestic and external can guarantee roof strength, but for roof strength can protect passenger
There are no specific conclusions both at home and abroad for safety in roll procedure, therefore the design is strong outside vehicle for the body structure of passenger car
It spends higher A and C column installation air bag to be supported vehicle body in vehicle body rolling, protects occupant.
Summary of the invention
In response to the deficiencies in the existing technology, the present invention provides substitutes outside a kind of passenger car vehicle based on rolling protection
Capsule and its control method solve to mitigate the injury that body side rebuilds or renovate pairs of occupant.
The present invention achieves the above technical objects by the following technical means.
